I agree completely with Nisbet and nick54 - this is very strange and quite discouraging. After many years being content with their 18M shares, why choose now to start unloading???
freelance - It may only be 2m shares, but I'm sure that amount of sells has stopped the rise in its tracks..... and even if it appears not to be aggressive selling, there is nothing to suggest that this won't be the end of it?
...just when my glass was starting to look slightly above half empty... ;-)
